Sinus pain come and go?

Hi all, I have had sinus pain for two months. It will come and go momentarily at random times in day. Not antibiotics have helped or steroid sprays. Could it be asthma or maybe reflux? 

Where is your sinus pain? Mine is in my maxillary sinuses and nose. It has come and gone but lately it’s coming on stronger and more consistent so back to the dentist to rule out teeth! I don’t know much about sinusitis as I never had issues. I don’t know what’s normal, what a little inflammation means. Some drs gives meds- I was just on 2 rounds no luck! My sinus dr didn’t prescribe them I got from primary dr.  There is a dr that specializes just in the sinuses. I always went to an ENT but there are drs that specialize just with the sinuses. He just told me to rinse with sinus rinse and that I should rule out teeth issues. So not sure where your pain is. Feel better.

It’s all over my head. Worst is behind my eyes and forehead. Guessing it’s either frontal or sphenoid
